Issue 1.0(2013-04-10) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 10 DRH Hardware Maintenance Guide 5 Replacing an Optical Module 5 Replacing an Optical Module Prerequisites An optical module implements optical-electrical conversion, enabling optical transmission between a DRH and other devices. You must disconnect optical fibers from an optical module before replacing the optical module. Disconnecting the optical fibers interrupts the transmission of CPRI signals. Confirm the type of a faulty optical module and do as follows:
Log in to the WebLMT or M2000 and run the DSP SFP command. Confirm the type of the faulty optical module according to the Transmission Rate, Wavelength, and Transmission mode fields in the query result and obtain an optical module of the same type. Figure 5-1 shows the label on the optical module. Figure 5-1 Label on the optical module
(1) Peak rate
(2) Wavelength
(3) Transmission mode If the software version does not support query of the type of the optical module by using an MML command, obtain all types of optical modules. If a fault in the optical module on the DRH side causes disconnection of the CPRI link, the MML command to query the type of the fault cannot be used. In this case, query the type of the corresponding optical module on the DCU side instead and obtain a new optical module of the same type. For the detailed querying method, see the DCU3900 Hardware Maintenance Guide. The following tools and materials are available: ESD gloves, M4 Phillips screwdrivers, and an ESD box or bag. Context Optical modules are inserted into CPRI ports on a DRH. Optical modules are hot-swappable when the same CPRI ports are used. Issue 1.0(2013-04-10) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 11 DRH Hardware Maintenance Guide 5 Replacing an Optical Module It takes about five minutes to replace an optical module on the DRH, which involves disconnecting optical fibers, removing the faulty optical module, inserting a new optical module, reconnecting the optical fibers, and waiting for CPRI links to resume. Procedure Step 1 Wear ESD gloves. Take proper ESD protection measures, for example, wear ESD gloves, to prevent electrostatic damage to the boards, modules, or electronic components. Step 2 Loosen the screws on the cover plate of the DRH cabling cavity using an M4 Phillips screwdriver, and then open the cover plate. Step 3 Record the connections of the optical module and optical fibers. Step 4 Press the latch on the optical fiber connector, and then remove the connector from the faulty optical module. Do not look into the optical fiber or optical module without eye protection after the optical fiber is removed from the optical module. Step 5 Lower the puller on the faulty optical module, and then pull the puller until the optical module is removed from the DRH. Step 6 Choose the optical module of the same type as the faulty optical module according to the label on the module. Install the new optical module into the DRH. The optical modules to be installed must match CPRI rates. Step 7 Insert the optical fiber connector into the new optical module. Step 8 Check the operating status of the new DRH by observing the status of DRH indicators. For details about the status of indicators, see section "DRH Indicators" in the DRH Hardware Description. Step 9 Reconnect the cables in the cabling cavity. Step 10 Close the cabling cavity of the DRH and use an M4 Phillips screwdriver to tighten the screws on the cover plate for the cabling cavity. Step 11 Take off the ESD gloves, and pack up all the tools.

Issue Draft A () Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd.. 72 DRH Installation Guide 8.1 Cabling Requirements 8 Installing DRH Cables Cables must be routed according to the specified cabling requirements to prevent signal interference. If a cable listed below is not required, skip the routing requirements of the cable. General Cabling Requirements Requirements for Bending Radius The bending radius of the 7/8'' feeder must be more than 250 mm (9.84 in.), and the bending radius of the 5/4'' feeder must be more than 380 mm (14.96 in.). The bending radius of the 1/4'' jumper must be more than 35 mm (1.38 in.). The bending radius of the super-flexible 1/2'' jumper must be more than 50 mm (1.97 in.), and the bending radius of the ordinary 1/2'' jumper must be more than 127 mm (5 in.). The bending radius of the power cable or PGND cable must be at least three times the diameter of the cable. The bending radius of a fiber optic cable is at least 20 times the diameter of the fiber optic cable, and the minimum bending radius of the breakout cable at each end of the fiber optic cable is 30 mm (1.18 in.). The bending radius of the signal cable must be at least five times the diameter of the cable. Requirements for Cable Binding The same types of cable must be bound together. Different types of cable must be separately routed with the minimum spacing of 30 mm
(1.18 in.) and cannot be entangled. The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged. Cable ties are installed in the same direction, and those at the same horizontal line must be in a straight line. The excess of indoor cable ties is trimmed off, and the excess of outdoor cable ties allows about 5 mm (0.2 in.), without remaining rough edges. Labels or nameplates must be attached to both ends, joints, or turns of cables after they are installed. Security Requirements Cables should be placed away from sharp objects or wall burrs. If these positions are inevitable, protect the cables with protection pipes. Cables must be routed away from heat sources, or heat-insulation materials are added between cables and heat sources. Sufficient slack (recommended for about 0.1 m [0.33 ft]) is provided in cables at turns or the position close to a device, facilitating cable and device maintenance. Outdoor Cabling Requirements Cables routed outdoors must be led through a pipe when they may be damaged. AC power cables, transmission cables, and cables buried in the ground must be protected. Issue Draft A () Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd.. 73 DRH Installation Guide 8 Installing DRH Cables If cables at the cabinet bottom need to be routed through a pipe along the ground, lead the pipe into the cabinet base for about 30 mm (1.18 in.) to 50 mm (1.97 in.), not into the cabinet. Block the pipe with waterproof tape or silicon gel, and secure the pipe to the cable hole at the cabinet bottom with metal piece. If cables at the cabinet bottom need to be routed through a pipe along the metal cable trough, do not lead the pipe into the cabinet base. The cable trough must be sealed and routed through the cable hole at the cabinet bottom. Cables are secured with cable clips. Cables are routed neatly along the specified cabling direction and secured with cable clips. The positions for cable clips are determined onsite. For example, the cable clips for the 7/8" feeder are installed at the spacing of 1.5 m (4.92 ft) to 2 m (6.56 ft) in the same direction, and the cable clips for the power cables are installed at the spacing of 1.5 m
(4.92 ft) to 2 m (6.56 ft) in the same direction. Cable clips must be vertical with cables, and the cables in a cable clip must be parallel. After routing cables neatly and correctly, tighten the screws on cable clips. Secure cables on the cable tray, as shown in Figure 8-1. Figure 8-1 Securing cables on the cable tray Special Cabling Requirements Cabling Requirements for Power Cables Issue Draft A () Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd.. 74 DRH Installation Guide 8 Installing DRH Cables Power cables must be installed in the position specified in engineering design documents. If the length of power cables is insufficient, replace the cables rather than adding connectors or soldering joints to lengthen the cables. Cables must be routed by only qualified and trained personnel before all preparations are made. Cables are routed in an untangled and orderly fashion. Cabling Requirements for PGND Cables PGND cables for the base station must be connected to the same ground bar. PGND cables must be buried in the ground or routed indoors. They should not be routed overhead before they are led into the equipment room. The exterior of the coaxial wire and the shield layer of the shielded cable must have proper electrical contact with the metal surface of the equipment to which they are connected. PGND cables and signal cables must be installed in an untangled and orderly fashion. A certain distance must be reserved between them to prevent interference from each other. Fuses or switches must not be installed on the PGND cables. Other devices must not be used for electrical connections of the PGND cables. All the metal parts in the housing of the equipment must be reliably connected to the ground terminal. Cabling Requirements for Fiber Optic Cables Fiber optic cables must be routed by at least three qualified and trained personnel before all preparations are made. Fiber optic cables are used within the temperature range of -40C to 60C. If the current temperature is out of the range, make protection measures or route the cables again. Cables are routed in an untangled and orderly fashion. Do not bind fiber optic cables at turns. Do not stretch, step on, or place heavy objects on fiber optic cables. Keep the cables away from sharp objects. When fiber optic cables are routed, the excess of the cables must be coiled around special devices, such as a fiber coiler. When coiling fiber optic cables, apply even strength. Do not bend the cables with force. Vacant optical connectors must be covered with dustproof caps. Fiber optic cables cannot be squeezed by the cabinet door when routed through the cabinet, as shown in Figure 8-2.

3918B&3921A&3921B&3926A Hardware Description Figure 2-2 DRH dimensions 2 DRH Introduction 2.2 DRH Functions This section describes the main functions of the DRH. The Distributed Remote Head (DRH) performs the following functions:
Receives downlink baseband data from the DCU and sends uplink baseband data to the DCU. Receives RF signals from the antenna system, down-converts the signals to intermediate frequency (IF) signals, amplifies the IF signals, and performs analog-to-digital conversion. The transmit (TX) channel filters downlink signals, performs digital-to-analog conversion, and up-converts RF signals to the TX band. Multiplexes receive (RX) and TX signals on the RF channel, which enables these signals to share the same antenna path. It also filters the RX and TX signals. The DRH can be powered by the AC/DC power module. In this case, this DRH is called AC DRH. An DRH consists of a high-speed interface unit, signal processing unit, power amplifier, and dual-duplexer. Figure 2-3 shows the logical structure of the DRH. Issue DraftA (2013-08-10) Huawei Proprietary and Confidential 3 Copyright Huawei Technologies Co., Ltd.. DRH3980A&3909A&3918A&
